SEWING-MACHINE RUFFLER.

SPECIFICATION forming part of Letters Patent No. 292,813, dated February5, 1884.

' Application filed 0ctober 1331883.: (ModeL) T0 at whom it may concernBe it known that I, JoHN HEBERLING,'2L citizen of the United States,residing at Mount Pleasant, in the county of Jefferson and State ofOhio, have invented certain new and useful Improvements in Rufflers; andI-do declare the following to be a full, clear, and eX- act descriptionof the invention, such as will enable others skilled in the art to whichit appertains to'make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in rufflers, and hasreferencemore particularly to that class of ruffling attachments inwhich positive motion is communicated to the ruffling-blade in bothdirections through the action of the needle-bar upon cams or levers. Itcomprises a frame usually adapted to be attachcdto the presser-bar of asewing-machine,

two adjustable cam-levers for receiving inothe device.

In most ruffling devices now in use the movement of the ruffling-bladeis regulated or adjusted in one direction only-that is, theruffling-blade in the forward movement always advances to the same placewith respect to the needle, and its stroke is made longer or shorter bydevices which vary the limit of the backward movement only. Experiencehas demonstrated that a better effect is obtained by increasing thestroke of the ruffling-blade in both directions from the needle inworking longer gathers, or decreasing it in both directions with respectto the needle in making shorter gathers; but the increase or decrease inthe distance the ruffling-blade passes beyond the needle in making fullor scant gathers should be less in proportion than the increase ordecrease in the distance it moves back from the needle to secure anewhold upon the goods. In this invention,therefore, means are provided forlengthening and shortening the distance the ruffling. blade moves bothforward and backward from the needle simultaneously by one movement ofthe adj listing-lever, and also for maintaining the deing drawings,making a part of this specification, in which Figures 1 and 2 are sideviews, and Fig. 3 is a plan view of the ruffler. Fig. 4 is a detailview, in perspective, of the ruffling-lever.

Fig. 5 shows a modification, and Fig. 6 shows in detail theconstruction. and manner of connecting the cams shown in Fig. 5.

The standard A and base-plate A constitute the supportingframeiof myruffler. The base is adapted at a to be secured to the presser-foot barof a sewing-machine, as is common in ruffiers. It is also provided,preferably, with the shield a, such as is used in ordinary rufilers.This latter, however, it will beunderstood, may be attached to thebed-plate of the machine when so desired.

The lever B is pivoted on pin-b to the standard A, near the upper end ofsame,and is provided with an extension, B, above and in rear of saidpivot, which is formed with notches b, which serve as a rack to hold thecam-op eratingarm at any desired point. On the lower end of the lever B,I bend or otherwise pro- ,vide the lateral arm 13 which extendshorizontally, as shown, and has the ruffling-blade 13 secured at one endto its end, 'asshown. This blade is preferably made of flat springmetal, and its forward or free end is bent down slightly, and serratedor otherwise suitably formed to grip the fabric when it is moved forwardthereon. This blade also has a slot, If, formed in its forward end, toenable it to pass the needle, as is desirable.

The cams D C are pivoted on pins (1 e to the lever 13 both in advance ofand respectively above and below the pivot 11 of said lever. The cam 0extends down from the pivot c, and is provided with an upward extension,0, which serves as a lever to adjust the cams, as will be presentlydescribed. This lever O is provided with a portion, 0, which engages thenotches b, and the lever is made with suf ficient spring to enable itsadjustment into engagement with any of said notches at will. 011 theupper edge of the cam G, in the region of its pivot c, I form the lip 0which enters the notch d, formed in the depending extension D of cam D,thus connecting the two cams, as will be readily seen. These cams, itwill be understood, are arranged in the path of the needle-clamp of themachine needle-bar, and are engaged by the same in its upward anddownward motions, which force the cams, firstone and then the other,back, giving the lever the desired rocking or swinging motion on itspivot. It will be seen, then, that moving the adjusting-lever C downthrows the cam 0 forward, so its contact with the needle bar will begreater, and the pendent lever B, with 'the rattling-blade 13 attachedthereto, will be carried back farther with the downward stroke of theneedle-bar, and as the camlevers C and D are geared together at c d, itis evident that the downward movement of the adjusting-lever C will alsothrow the upper cam D forward, thus bringing it in greater contact withthe needle-bar in its upward movement, carrying the lever B and therutfling-blade 13 further forward, all of which adjustments of the camsare indicated in dotted lines, Fig. 1. It follows, then, that by movingthe adj listing-lever 0 up both the cam-levers O and D will be movedback simultaneously, and are thus brought in slighter contact with theneedle-bar, and the stroke of the ruffiingblade B" shortened in thedistance it moves both forward of and back from the needle. Thus thestroke of the rattling-blade B is simultaneously lengthened andshortened by a single movement of the adj ustinglever G, and full orscant gathers accordingly made, as desired.

Either or both of the cam-levers C or D may have an extensionadjusting-lever, and various modifications of the form of the pendentarm or lever I3 may be used; also, the cam levers or prongs G and Dattached thereto, as shown in Fig. 5, all of which come within the scopeof my invention.

In Fig. 5 the rattling-blade lever is provided with an extension infront as well as in rear of its pivot. The cams are pivoted on the outerend of the forward extension. The upper one, E, is provided with a smallslot, E, in its lower end, and laps on the upper end of the lower cam, EFrom the latter I project a small pin or stud, E, which enters the slotE. The lower cam has an adj listing-lever which engages the rack andenables the adjustment of the two cams, as will be readily understood.

It will be appreciated that the arrangement shown in Fig. 5 is differentfrom that shown in the other figures in form and immaterial arrangementonly.

It is obvious that the gearing of the cams might be modified in variousways. I prefer, however, the gearing mechanism shown in Figs. 1, 2, 3,and 4, as thereby an easily-operated device is provided.

It will be appreciated that instead of conneeting the cams and adjustingthem by the same devices the said cams might be secured directly to thelever, as shown, and detached or separated at their inner ends. In thiscase the cams would need to be adjusted separately, to vary the throw ofthe ruflling-blade, as will be understood.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. The combination, with the pivoted ruffling -blade lever, of two camspivoted independently to the said lever, and means, substantially asdescribed, whereby they may be simultaneously and correspondinglyadjusted on their pivots to any suitable angle relative to theblade-lever, substantially as and for the purposes specified.

2. In a rufller or gatherer, the combination of the pivotedrufliing-blade lever, the cams C D, pivoted to said lever, both saidcams being adjustable independently of the lever, and means foradjusting the cams, substantially as specified.

8. The combination, in a ruffler or gatherer, of a pivoted lever andcams pivoted to the said lever, and connected substantially asdescribed, whereby the adjustment of one accomplishes a correspondingadjustment of the other cam, as set forth.
